Angle Stop FS-WA/90° vs Angle Stop FS-WA

Trying to decide between these two. I realized one is fixed and one not, and the FS-WA has detents at multiple angles including 90°. I also know that I do not do so much 90° cutting that I need a dedicated guide just for that. That said Ive never used the FS-WA and don't know what I don't know.For anyone that has owned/used both, what should I be aware with either? Is the FS-WA/90° even worth getting at this point now that the FS-WA is out? Does the FS-WA have issues holding solid at its pre-detented angles?

FWIW, in the USA, it seems these two are about the same price, so cost is not a factor.

In the USA that squaring arm is sold by the patent holder,TSO.  Elsewhere is is sold as a  Festool accessory. I have the TSO unit.  It mounts quickly with no tools or components to lose and has been shown to be accurate each time.

I have no experience with the adjustable version.
